IMPROVEMENT IN ELASTIC FABRICS.

Specification forming part of Letters Patent No. 170,572, dated November30, 1875; application filed November 1, 1875.

To all whom it may concern:

Be it known that we, MOSES H. LEONARD, of East Hampton, in the county ofHampshire and State of Massachusetts, and JOHN H. BUGKLEY, of EastHampton, in the county of Hampshire and State of Massachusetts, haveinvented a new and useful Improvement in Elastic Fabrics; and we dohereby declare that the following is a full and exact description of thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon.

This invention is an elastic fabric, which has its central elastic cordscovered by auxiliary warp-stock, and its edge-cords covered byweft-threads only, the advantages of which will be fully describedhereafter.

In the drawings, 860., Figure 1 represents a transverse section of ourimproved fabric;

Fig. 2, a longitudinal section of the same; Fig. 3, a side elevation ofthe fabric, and Fig. 4 a partial perspective view of the same.

To enable others to make this fabric, I will proceed fully to describethe same.

a a represent a series of central elastic cords. a a represent the upperand lower faces of the fabric, each of which is formed of a double warp,as shown. a represents an intermediate binding-thread, by means of whichthe two faces are united together. 00

represents an edge-cord, which is covered by the weft-thread so only, asshown.

A fabric formed with double-warp faces, or double-warp faces and back,united by an intermediate binding-thread working against the rubbercord, is well known as terryand suspender or garter webbing, the'ahxiliary warp-stock being introduced to protect the rubber from heatand wear, and also to give a desirable finish to the goods. This,however, as heretofore made, has its edge-cords covered also with theauxiliary warp-stock in a similar manner to the central portion. Thefabric thus made possesses certain serious defects, which this inventionis designed to remedy.

It is found in practice, when the edge-cords are covered by theauxiliary warp-stock, that it is impossible for them to draw up thestock with which they are covered to asgreat an extent as the centralcords, so hat the cen tral portion is less in length than the edge, and,consequently, the goods have a cockled appearance. This results, ofcourse, from the fact that the edge-cords have proportionally more stockto contract than the intermediate ones, and it may be remedied in partby increasing the size or number of the edge-cords; but this necessarilyincreases also the trouble and expense.

Another defect arises in the ordinary fabric from the drawing in of theedge-cords into the body of the material, which efl'ect results from thefact that the rubber lies in a smooth tube or bag, which has no stronghold upon it. When the edge-cord is held by weft-threads only, however,each single turn of the thread is embedded in the rubber, and helps tohold it securely in place.

' From the foregoing it will be understood that, by means of theinvention described, a fabric is provided which possesses all theadvantages of the old without its defectsthat is, it may be so woven asto lie perfectly flat without a cockled edge, and its edge-cords aresecurely held from drawing into the material.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is

A fabric having its central elastic cords covered by auxiliarywarp-stock, substantially as described, and its edge-cords byweft-threads only, substantially as described.
